Feeding the whole office?
Past 20 people, compare catering on cost per head before you order a tower of pizza boxes. Someone else brings the plates.
Same crowd, different appetites
These follow the calculator above, so they change with the size and the headcount.
How we got to 3
7 grown-ups at 3 slices each need 21 slices. We add 10% so nobody’s left eyeing the last one, which makes 24. A large pizza has 8 slices, which is what Pizza Hut and Papa John’s cut theirs into, so 24 ÷ 8 = 3, exactly 3 pizzas with no rounding.
How to split 3 pizzas
We’d go 1 cheese, 1 pepperoni and 1 veggie or specialty. Cheese is the safe bet for kids and picky eaters, and the veggie pizzas cover anyone who skips meat. If you know your crowd, move pizzas between the three; the total stays the same.
Pizzas for 7 people by size
| Size | Slices in one | Pizzas for 7 | Slices in all |
|---|---|---|---|
| small | 6 | 4 | 24 |
| medium | 8 | 3 | 24 |
| large | 8 | 3 | 24 |
| extra-large | 12 | 2 | 24 |
The same 24 slices, divided by what each size holds and rounded up. Pick a size in the calculator above and the answer follows.
7 people, if some of them are kids
| Who’s coming | Grown-ups | Kids | Large pizzas |
|---|---|---|---|
| All grown-ups | 7 | 0 | 3 |
| A quarter kids | 5 | 2 | 3 |
| Half kids | 3 | 4 | 3 |
| Three-quarters kids | 2 | 5 | 3 |
Kids under 12 count 2 slices each, grown-ups 3. 7 kids on their own need 2.
Serving other food too?
Serving wings, salad or sides? We count 75% of the usual slices when there’s other food, which brings 7 grown-ups down to 3 large pizzas. Tick “Also serving wings, salad or other food” above to see it.

Ordering for a teen sleepover, a roommate night or a birthday dinner
For a roommate night, 3 large pizzas is one order on one card, and the cost table above works out each person’s share at a few example prices, so settling up takes one message to the group chat.
For a birthday dinner, time the pizza for when everyone sits down and leave the cake for after; nobody has room for both at once. With 1 cheese, 1 pepperoni and 1 veggie on the table, the birthday person gets first pick, which is most of the point of a birthday.
